BUNG- EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 293,661, dated February 19, 1884.

Application filed October 29, 1883. (No model.)

fo all wiz/0711l it may concern:

Beit known that I, ADELBERT H. MCKEAN, a citizen of the United States, residing at Trumansburg, in the county of Tompkins and State of New York, haveinvented a new and useful Bun g-Extractor, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to bung-pullers, or devices for extracting bun'gs from barrels and casks; and it has for its object to produce a device for this purpose which shall be simple in construction, inexpensive, easily manipulated, certain in operation, and by the use of which wooden bungs of the ordinary kind may be extracted without injury to the cask.

To this end my invention consists in certain improvements in the construction of the said device, which will be hereinafter fully described, and particularly pointed out i-n the claims.

In the drawings hereto annexed, Figure l is a perspective view of my improved bungpuller. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a vertical transverse sectional view on the line x in Fig. 2. Fig. 4 is a view illustrating the method of starting-the hole for the screw, and Fig. 5 is a view illustrating the operation of the extracting device.

The salneletters refer to all the figures.

A in the drawings designates a suitable lever or handle, formed with an opening or handhold, B, a fulcrum-stud, C, and a head, D, extending beyond the said fulcrum-stud. AThe fulcrum-stud is rounded, as shown, and is provided on its under side with a rib or flange, E, which, when the device is in use, slightly enters the wood of the cask or barrel, thus preventing the lever from slipping or from being the same parts in laterally displaced. The head D has a transverseopening, F, in which Vis seated a cylindrical plug, G, having a projecting conical point, H, at one end, and provided with a vertical perforation, I, in which is seated a screw, J, projecting through slots K K in the upper and lower sides of the head, thus permitting the plug to partly turn in its bearing. The screw'J is held securely in the plug Gby means of a pin, L, entering through an opening, M, in the blunt end of the plug, and engaging an opening or recess, N, inthe side of the said screw. The pin L is held in position in the plug G by means of a transverse conical pin or wedge, O.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed.F The pointed end of the plug G is first placed over the bung, into which it is driven by a sharp blow of a hammer against the upper blunt end of the said plug, thus forming an opening, which serves to start the screw J. The latter, being placed in the said opening in the position shown in Fig. 5 ofthe drawings, is turned and driven into the bung, the handle A serving as a lever or wrench wherewith to turn it. When the screw has been drivenl sufficiently into the bung, the lever A is fulcrumed .upon the istud C, and pressed in a downward direction, thus easily starting and extracting` the bung.

I claim as my invention and desire to secure by Letters Patent of the United Statesl. As an improvement in bung-extractors, the herein described device, comprising a handle orv lever constructed with a fulcrumstud and with a transversely-perforated head, a plug seated in the said head where it may partially revolve, and a screw extendin-g through said plug and through slots in the said head,'with means for holding the screw in place, as set'forth.

2. As an improvement in bung-extractors,

a device comprising alever or handle having a fulcrum-stud, a head, a plug seated in"said head and having a conical point extending beyond the same, and a screw passing vertically through said plug, with means for holding the screw in place, substantially as set forth.

3. In abung-extractor, the herein-described lever or handle provided with a fulcrumstud having on its under side a rib or flange, substantially as and for the purpose set forth.

4. A bung-extractor comprising a lever or handle having a transversely-perforatedhead having slots in its upper and lower sides, a plug seated in said head and having lat one end a projecting conical point and at the IOO other end a longitudinal recess, a screw passing through the said plug and through the slots in the head, and having a recess in one side, a pin entering the recess in the plug and engaging the recess in the side of the screw, and a pin or wedge driven transversely through the plug and retaining the pin in the latter, as set forth.

5. The herein-described improved bung-extractor, the same comprising the lever or handle having an openin g or hand-hold, a rounded fulcruin-lug having a rib or flange on its under side and a transverselyperiorated head, a plug seated in said head and having an ex- ADELBERT ll. MCKEAN.
